Why not just buy a cable that is made for subs? I bought a Kimber Kable Cadence cable that works just fine, and is reasonably priced. 2 meters with WBT connects is around $225 at the Cable Company. WBT's are great. But if you want just RCA connects, it's about $170 for a 2 meter cable.
DIY Spekon Cable For Rel
I’m looking to make a pair of speakon cables for my Rel subs. I could really use some advice on what would be good choices for this type application. The cable hooks to the amp outputs but from what I understand is just carrying low level signals. I am not sure if a shielded cable would be ideal or just a twisted pair of high quality wire. I run them as a stereo pair so only need two wires and 8-10ft long. I’m not looking to spend a lot maybe $100-200 but less would be better. I have 50ft of 12awg silver plated PTFE ofc that I’ve debated using. Just seems excessive for the application I suppose. I believe the stock cable Rel provides is only 24awg. Anyways would love any thoughts or opinions on the matter. I really don’t have a lot of knowledge when it comes to cabling. Thanks!
